It's the feature.

---------------------------------------------------------------- IO#puts
     ios.puts(obj, ...)    => nil
------------------------------------------------------------------------
     Writes the given objects to _ios_ as with +IO#print+. Writes a
     record separator (typically a newline) after any that do not
                                                           ~~~~~~
     already end with a newline sequence. If called with an array
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     argument, writes each element on a new line. If called without
     arguments, outputs a single record separator.
